We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

- Age 18 years or over

- Able to provide written informed consent

- Willing and able to comply with the protocol for the duration of the study
Minimum age
18 Years
Maximum age
No limit

Can healthy volunteers participate?
Yes
Key exclusion criteria
- History of serious vaccine allergy*

- History of vasculitis, Wegener's granulomatosis, narcolepsy, Guillain Barre, SLE or
other systemic autoimmune disease that in the opinion of the investigator would make
the vaccine contraindicated

- History of chronic liver disease or liver transaminases elevated more than 3xULN

- Women of childbearing potential, unless using a reliable and appropriate contraceptive
method, specifically oral contraceptive pill, IUD or mechanical barrier device.

- Pregnant or lactating women.

- Any serious medical, social or mental condition which, in the opinion of the
investigator, would be detrimental to the subjects or the study.

- Receipt of another investigational agent within 28 days preceding initiation of
treatment.

- Individuals who have a past history of potential vaccine reactions will be
assessed by the investigator, who will decide whether any past potential
vaccine-related side are sufficiently minimal to allow vaccine administration to
proceed.

Summary
Brief summary
Recombinant H7 (rH7) vaccine has been shown to be poorly immunogenic in previous human
clinical trials. This study will test approaches to improve the immunogenicity of H7 vaccine,
namely use of a three dose regimen, use of a modified H7 HA sequence from which the Tregitope
has been removed (rH7m), and inclusion of delta inulin adjuvant adjuvant in the vaccine
